Japanese Patent JP4446263
Kind Code:
B2
Abstract:
A force sensor has an elastically deformable carrier (10; 110) which absorbs the force to be measured and on which there are a first and a second strain measurement element (21, 31; 121, 131) arranged such that the elastic deformation of the carrier (10; 110) which is caused by the force leads to different elongations in the two strain measurement elements (21, 31; 121, 131). This difference in elongations is used as a measure for the force to be measured. The force sensor as claimed in the invention is largely immune to disruptive ambient influences such as temperature changes, electromagnetic interference, tensile, compressive and/or shearing forces in the lengthwise direction of the tube, shearing forces transversely to the lengthwise direction of the tube, etc. Wheel load scales with several force sensors as claimed in the invention have such a short response time that it enables measurement of the wheel loads of moving vehicles.
